Question 1 of 27070

Q

Which of the valves listed below is best suited for throttling service?

🔍 Key Concepts

• Flow control characteristics of common valve types (plug, globe, gate, butterfly valves) • Difference between throttling (regulating flow) and fully open/fully closed service • How valve design affects pressure drop and wear when partially open

💭 Think About

• Think about which valve type is specifically designed to operate partially open for long periods without being damaged. • Consider how precisely each valve type can control small changes in flow rate— which one gives the most accurate control? • Ask yourself: which valve is usually recommended in engineering texts for regulating flow, not just start/stop?

✅ Before You Answer

• Identify which valves are mainly for on/off (full open/full closed) service and usually NOT recommended for throttling. • Recall which valve has a disc (or plug) that moves linearly against the flow, changing the flow path gradually and predictably. • Make sure the valve you choose is commonly used where frequent adjustment of flow is needed, such as control lines or cooling water systems.
